However, the shape and structure of the rear part of the door lower garnish 19 and the side sill garnish 18 of the rear door 12 are in the front-rear direction. Symmetrical shape and structure.
　フロントドア１１の前端を超えてフロントフェンダーパネル１４の下方に延びるサイドシルガーニッシュ１８の前部から突出部１８ｈが上向きに突出するとともに、リヤドア１２の後端を超えてリヤフェンダーパネル１５の下方に延びるサイドシルガーニッシュ１８の後部から突出部１８ｈが上向きに突出しており、これらの突出部１８ｈの車幅方向外面はフロントフェンダーパネル１４の下部およびリヤフェンダーパネル１５の下部に滑らかに連続している。 A side sill extending below the front fender panel 14 beyond the front end of the front door 11 has a projection 18h projecting upward from the front of the garnish 18 and a side sill extending below the rear end of the rear fender panel 15 beyond the rear end of the rear door 12. Projections 18 h project upward from the rear of the garnish 18, and the outer surfaces of these projections 18 h in the vehicle width direction smoothly continue to the lower part of the front fender panel 14 and the lower part of the rear fender panel 15.
　そしてサイドシルガーニッシュ１８の前端の突出部１８ｈの上縁とフロントフェンダーパネル１４の下縁との間の見切り線３１と、その後方に位置するフロントドア１１およびリヤドア１２のドアロアガーニッシュ１９の上縁とドアアウターパネル１３の下縁との間の見切り線３３と、その後方に位置するサイドシルガーニッシュ１８の後端の突出部１８ｈの上縁とリヤフェンダーパネル１５の下縁間との見切り線３２とは、車幅方向に見て直線状に整列している（図１参照）。 The parting line 31 between the upper edge of the protrusion 18 h at the front end of the side sill garnish 18 and the lower edge of the front fender panel 14, and the upper edges of the door lower garnish 19 of the front door 11 and the rear door 12 located behind the same. The parting line 33 between the lower edge of the door outer panel 13 and the parting line 32 between the upper edge of the protrusion 18 h at the rear end of the side sill garnish 18 and the lower edge of the rear fender panel 15 located behind the parting line 33. Are aligned in a straight line when viewed in the vehicle width direction (see FIG. 1).
　また前後方向に見たとき、ドアロアガーニッシュ１９の車幅方向外壁１９ａおよびサイドシルガーニッシュ１８の車幅方向外壁１８ａの外壁上部１８ｂは、サイドシルガーニッシュ１８の突出部１８ｈの車幅方向外面に対して車幅方向内側に後退しているため（図２参照）、フロントドア１１およびリヤドア１２のドアロアガーニッシュ１９と、その下方に沿うサイドシルガーニッシュ１８の外壁上部１８ｂとは、フロントフェンダーパネル１４の後端からリヤフェンダーパネル１５の前端に亘って前後方向に帯状に延びる略三角形断面の浅い凹部３４を構成する（図１の鎖線参照）。 Further, when viewed in the front-rear direction, the outer wall upper portion 18b of the vehicle width direction outer wall 19a of the door lower garnish 19 and the vehicle width direction outer wall 18a of the side sill garnish 18 are positioned at a distance from the vehicle width direction outer surface of the protrusion 18h of the side sill garnish 18. Since it has receded inward in the width direction (see FIG. 2), the lower door garnish 19 of the front door 11 and the rear door 12 and the upper outer wall 18 b of the side sill garnish 18 along the lower side are separated from the rear end of the front fender panel 14. A shallow recess 34 having a substantially triangular cross-section extending in the front-back direction across the front end of the rear fender panel 15 is formed (see a chain line in FIG. 1).
　その結果、サイドシルガーニッシュ１８の前側の突出部１８ｈの後端には前記凹部３４の前端が臨む略三角形状の後向きの縦壁１８ｉが形成され、同様にサイドシルガーニッシュ１８の後側の突出部１８ｈの前端には前記凹部３４の後端が臨む略三角形状の前向きの縦壁１８ｉが形成される。 As a result, a substantially triangular rearward vertical wall 18i facing the front end of the concave portion 34 is formed at the rear end of the front projection 18h of the side sill garnish 18, and similarly, the rear projection 18h of the side sill garnish 18 is formed. At the front end, a substantially triangular front-facing vertical wall 18i facing the rear end of the recess 34 is formed.
　次に、上記構成を備えた本発明の実施の形態の作用を説明する。 Next, the operation of the embodiment of the present invention having the above configuration will be described.
　自動車の走行中にタイヤが路面から小石等を撥ね上げ、その小石等が鋼板製のドアアウターパネル１３の下縁に衝突すると、塗装が剥げて鋼板に錆が発生する原因となる問題がある。しかしながら、本実施の形態によれば、ドアアウターパネル１３の下部をドアロアガーニッシュ１９で覆ったことにより、小石等との衝突によるドアアウターパネル１３の損傷を防止することができる。ドアロアガーニッシュ１９は合成樹脂製であるため、小石等との衝突により傷ついても錆が発生する虞はない。 (4) When the tire repels pebbles and the like from the road surface while the automobile is running and the pebbles collide with the lower edge of the door outer panel 13 made of a steel plate, there is a problem that the paint is peeled off and rust is generated on the steel plate. However, according to the present embodiment, since the lower portion of the door outer panel 13 is covered with the door lower garnish 19, it is possible to prevent the door outer panel 13 from being damaged by collision with pebbles or the like. Since the door garnish 19 is made of a synthetic resin, there is no possibility that rust will be generated even if the door garnish 19 is damaged by collision with pebbles or the like.
　ドアロアガーニッシュ１９の下縁およびサイドシルガーニッシュ１８の上縁の境界部において、仮にドアロアガーニッシュ１９の下縁の位置がサイドシルガーニッシュ１８の上縁の位置に対して車幅方向内側にオフセットしている場合、自動車の近くに立った人の目線でサイドシルガーニッシュ１８の上向き面である上壁１８ｄの一部が見えるため、光を反射しないために暗く見える境界部と光を反射するために明るく見える上壁１８ｄとが隣り合って目立ってしまい、外観上のノイズとなって美観を低下させる可能性がある。 At the boundary between the lower edge of the door garnish 19 and the upper edge of the side sill garnish 18, the position of the lower edge of the door lower garnish 19 is temporarily offset inward in the vehicle width direction with respect to the position of the upper edge of the side sill garnish 18. In this case, a part of the upper wall 18d, which is the upward surface of the side sill garnish 18, can be seen from the eyes of a person standing near the car, so that the boundary that looks dark because it does not reflect light and that looks bright because it reflects light The wall 18d may be conspicuous adjacent to the wall 18d, resulting in noise on the external appearance and deteriorating the aesthetic appearance.
　しかしながら、本実施の形態によれば、ドアロアガーニッシュ１９およびサイドシルガーニッシュ１８の境界部において、ドアロアガーニッシュ１９の下縁の位置がサイドシルガーニッシュ１８の上縁の位置に対して車幅方向外側に距離αだけオフセットしているので、自動車の近くに立った人の目線でサイドシルガーニッシュ１８の上向き面である上壁１８ｄが見えなくなり、境界部が目立たなくなって美観が向上する。 However, according to the present embodiment, at the boundary between the door lower garnish 19 and the side sill garnish 18, the position of the lower edge of the door lower garnish 19 is separated from the position of the upper edge of the side sill garnish 18 by a distance outward in the vehicle width direction. Since it is offset by α, the upper wall 18d, which is the upward surface of the side sill garnish 18, cannot be seen from the eyes of a person standing near the car, and the boundary is less noticeable, improving the appearance.
　またサイドシルガーニッシュ１８の前部および後部は上向きに突出する突出部１８ｈを備えており、前側の突出部１８ｈの上縁およびフロントフェンダーパネル１４の下縁間の見切り線３１と、後側の突出部１８ｈの上縁およびリヤフェンダーパネル１５の下縁間の見切り線３２とは、ドアロアガーニッシュ１９の上縁およびドアアウターパネル１３の下縁間の見切り線３３と直線状に整列しているので、それらの見切り線３１，３２，３３がフロントフェンダーパネル１４、フロントドア１１のドアアウターパネル１３、リヤドア１２のドアアウターパネル１３およびリヤフェンダーパネル１５に跨がるように直線状に連続してデザイン上の特徴となり、見切り線３１，３２，３３の周辺の凹凸が目立たなくなって美観が向上する。 The front and rear portions of the side sill garnish 18 are provided with protrusions 18h projecting upward. A parting line 31 between the upper edge of the front protrusion 18h and the lower edge of the front fender panel 14, and the rear protrusion Since the parting line 32 between the upper edge of 18h and the lower edge of the rear fender panel 15 is linearly aligned with the parting line 33 between the upper edge of the door lower garnish 19 and the lower edge of the door outer panel 13, On the design, the parting lines 31, 32, and 33 are linearly and continuously connected to the front fender panel 14, the door outer panel 13 of the front door 11, the door outer panel 13 of the rear door 12, and the rear fender panel 15. The unevenness around the parting lines 31, 32, and 33 is not noticeable, and the appearance is improved.
　特に、樹脂製のサイドシルガーニッシュ１８およびドアロアガーニッシュ１９を例えば艶消しの黒色とし、フロントフェンダーパネル１４、フロントドア１１のドアアウターパネル１３、リヤドア１２のドアアウターパネル１３およびリヤフェンダーパネル１５を車体色とすれば、一直線状の見切り線３１，３２，３３が一層強調されるために更に効果的である。 In particular, the resin side sill garnish 18 and the door lower garnish 19 are, for example, matte black, and the front fender panel 14, the door outer panel 13 of the front door 11, the door outer panel 13 of the rear door 12, and the rear fender panel 15 are colored in the body color. This is more effective because the straight parting lines 31, 32, 33 are further emphasized.
　またドアロアガーニッシュ１９と、サイドシルガーニッシュ１８の車幅方向外壁１８ａの外壁上部１８ｂとにより、サイドシルガーニッシュ１８の前側の縦壁１８ｉから後側の縦壁１８ｉに亘って前後方向に帯状に延びる浅い三角形状断面の凹部３４が形成されるので、その帯状の凹部３４よりなる意匠面を構成して美観を高めることができる。 Further, the door lower garnish 19 and the upper outer wall 18b of the vehicle width direction outer wall 18a of the side sill garnish 18 form a shallow triangle extending in a front-rear direction from the front vertical wall 18i of the side sill garnish 18 to the rear vertical wall 18i. Since the concave portion 34 having the shape of the cross section is formed, the design surface including the band-shaped concave portion 34 can be formed to enhance the appearance.
　しかもドアロアガーニッシュ１９の下縁およびサイドシルガーニッシュ１８の上縁間のオフセットした境界部が前記凹部３４内に配置されるので、オフセットした境界部を目立たなくして美観を高めることができる。 In addition, since the offset boundary between the lower edge of the door lower garnish 19 and the upper edge of the side sill garnish 18 is arranged in the concave portion 34, the offset boundary can be made inconspicuous and the appearance can be enhanced.
　またサイドシルガーニッシュ１８の車幅方向外壁１８ａは、上側が車幅方向外側に向かって傾斜する外壁下部１８ｃと、外壁下部１８ｃの上方に連続して上側が車幅方向内側に向かって傾斜する外壁上部１８ｂとを備え、外壁下部１８ｃは前方に位置するフロントフェンダーパネル１４および後方に位置するリヤフェンダーパネル１５に滑らかに連続するので、サイドシルガーニッシュ１８の外壁下部１８ｃからフロントフェンダーパネル１４およびリヤフェンダーパネル１５に跨がる連続面が構成されて美観が向上する。 The outer side wall 18a of the side sill garnish 18 has an outer wall lower part 18c whose upper side is inclined outward in the vehicle width direction and an outer wall upper part whose upper side is inclined inward in the vehicle width direction continuously above the outer wall lower part 18c. 18b, the lower portion 18c of the outer wall smoothly continues to the front fender panel 14 located at the front and the rear fender panel 15 located at the rear, so that the front fender panel 14 and the rear fender panel 15 extend from the lower portion 18c of the outer side wall of the side sill garnish 18. A continuous surface straddling is formed, and the appearance is improved.
　またドアアウターパネル１３の下部に形成した凹部１３ｂにドアロアガーニッシュ１９を固定して閉断面を構成したので、閉断面構造によりドアロアガーニッシュ１９の剛性を高めることができるだけでなく、ドアアウターパネル１３およびドアロアガーニッシュ１９の車幅方向外壁１９ａを段差なく滑らかに連続させ、美観の向上および空気抵抗の減少を図ることができる。 Further, since the door lower garnish 19 is fixed to the concave portion 13b formed at the lower portion of the door outer panel 13 to form a closed section, not only the rigidity of the door lower garnish 19 can be increased by the closed section structure, but also the door outer panel 13 can be improved. In addition, the outer wall 19a in the vehicle width direction of the door lower garnish 19 can be smoothly and continuously connected without any step, so that the appearance can be improved and the air resistance can be reduced.
　またドアロアガーニッシュ１９は車幅方向外壁１９ａおよび下壁１９ｂを有するＬ字状断面であり、下壁１９ｂの車幅方向内端が、ドアアウターパネル１３をドアインナーパネル２５に結合する周縁ヘム加工部１３ａに当接するので、下壁１９ｂの車幅方向長さを長くすることでドアロアガーニッシュ１９の下縁の車幅方向外側へのオフセット量αを増加できるだけでなく、小石等の衝突によりドアロアガーニッシュ１９が受ける荷重をドアアウターパネル１３の強度の高い周縁ヘム加工部１３ａで確実に支持できる。 Further, the door lower garnish 19 has an L-shaped cross section having a vehicle width direction outer wall 19a and a lower wall 19b, and an inner end of the lower wall 19b in the vehicle width direction is a peripheral hemming for connecting the door outer panel 13 to the door inner panel 25. As the lower wall 19b is extended in the vehicle width direction, the offset amount α of the lower edge of the door lower garnish 19 to the vehicle width direction outside can be increased, and the collision of small doors causes the door to be in contact with the lower wall 19b. The load received by the lower garnish 19 can be reliably supported by the high-strength peripheral hemmed portion 13a of the door outer panel 13.
　またドアロアガーニッシュ１９は、車幅方向外壁１９ａの上端に設けられてドアアウターパネル１３に設けた段部１３ｃに当接する上部位置決め部１９ｃと、下壁１９ｂに形成された補強リブ１９ｅの車幅方向内端に設けられてドアアウターパネル１３に当接する下部位置決め部１９ｄと、上部位置決め部１９ｃおよび下部位置決め部１９ｄ間に設けられてドアアウターパネル１３に係合するクリップ２８を支持するクリップ座１９ｆとを備えるので、ドアアウターパネル１３に対するドアロアガーニッシュ１９の取付精度の向上と取付剛性の向上とを両立させることができる。 The door lower garnish 19 is provided at the upper end of the vehicle width direction outer wall 19a and has an upper positioning portion 19c which abuts a step 13c provided on the door outer panel 13, and a reinforcing rib 19e formed on the lower wall 19b. A lower positioning portion 19d provided at the inner end in the direction and abutting on the door outer panel 13, and a clip seat 19f provided between the upper positioning portion 19c and the lower positioning portion 19d to support a clip 28 engaged with the door outer panel 13. Therefore, it is possible to achieve both the improvement of the mounting accuracy of the door lower garnish 19 with respect to the door outer panel 13 and the improvement of the mounting rigidity.
　またサイドシルインナー２１およびスチフナ２２で構成されるサイドシル１７の骨格の上端の高さは、ドアロアガーニッシュ１９の上端の高さに略一致するので、ドアロアガーニッシュ１９を取り付ける凹部１３ｂをドアアウターパネル１３に形成したことでフロントドア１１およびリヤドア１２の下部の車幅方向厚さが減少して強度が低下しても、その強度低下をサイドシル１７の骨格の強度で補って耐側面衝突性能を確保できる。 The height of the upper end of the skeleton of the side sill 17 composed of the side sill inner 21 and the stiffener 22 is substantially equal to the height of the upper end of the door lower garnish 19. Even if the strength of the lower portion of the lower portion of the front door 11 and the rear door 12 in the vehicle width direction is reduced due to the formation, the strength reduction can be compensated for by the strength of the side sill 17 and the side impact resistance can be secured. .
　またサイドシル１７のスチフナ２２は、ドアロアガーニッシュ１９の下方で車幅方向外側に張り出す膨出部２２ａを備え、膨出部２２ａの車幅方向内面に補強部材２４が重ね合わされるので、補強部材２４でサイドシル１７の強度を高めて耐側面衝突性能を一層確実に確保できる。 Further, the stiffener 22 of the side sill 17 has a bulging portion 22a that projects outward in the vehicle width direction below the door lower garnish 19, and the reinforcing member 24 is superimposed on the inner surface of the bulging portion 22a in the vehicle width direction. 24 enhances the strength of the side sill 17 and more reliably secures the side impact resistance.
　以上、本発明の実施の形態を説明したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。 Although the embodiments of the present invention have been described above, various design changes can be made in the present invention without departing from the gist thereof.
　例えば、本発明は、フロントドア１１およびリヤドア１２の両方を備える自動車に限らず、フロントドア１１だけを備える自動車に対しても適用することができる。
  For example, the present invention is not limited to a vehicle having both the front door 11 and the rear door 12, and can be applied to a vehicle having only the front door 11.
